Vadim Makhorov and Raskalov Vitaliy say they climbed the 2,073-foot tower and a crane above it — peaking out at roughly 650 meters — on Chinese New Year.

“Ten days ago, during the celebration of Chinese New Year, the entire country was resting – all the people had vacations, so as the builders,” Makhorov wrote in a post. ”Everybody was squibbing in their neighborhoods and enjoying the holidays. For us, it was perfect time to climb the tower and a crane jib above it (the highest point is about 650 meters).”
